KEY MESSAGES
- WINDY CONDITIONS WILL EXIST THROUGH TUESDAY. WIND GUSTS OF 25
TO 50 MPH WILL BE COMMON, STRONGEST IN SOUTH-CENTRAL MT TODAY
AND EASTERN MT TUESDAY. THIS WILL CAUSE ELEVATED FIRE WEATHER
CONDITIONS TUESDAY.
- WARMER AND DRIER CONDITIONS RETURN MID-WEEK. OCCASIONALLY
BREEZY CONDITIONS WILL CAUSE LOCALIZED ELEVATED FIRE WEATHER
CONDITIONS.
- A PATTERN CHANGE TO COOLER WITH AN INCREASED CHANCE OF
PRECIPITATION RETURNS FRIDAY INTO THE WEEKEND. DETAILS REMAIN
UNCERTAIN. STAY UP TO DATE WITH THE LATEST FORECAST.
UPDATE
AN UPPER LOW CONTINUES TO MOVE THROUGH NORTHERN MONTANA THIS
EVENING. SHOWER AND THUNDERSTORM ACTIVITY ACROSS SOUTHERN MONTANA
AND NORTHERN WYOMING HAS LARGELY COME TO AN END. BREEZY WEST TO
NORTHWEST WINDS WILL CONTINUE THROUGH THIS EVENING AND OVERNIGHT.
THE CHANCE FOR PRECIPITATION OVERNIGHT IS LOW ACROSS THE AREA,
LESS THAN 15%. THE REST OF THE FORECAST REMAINS IN GOOD SHAPE.
MATOS
DISCUSSION
TODAY THROUGH SUNDAY...
A LOW PRESSURE SYSTEM WILL BRING ISOLATED TO SCATTERED SHOWERS
AND THUNDERSTORMS AND WINDY CONDITIONS TO THE AREA TODAY. THESE
SHOWERS AND THUNDERSTORMS ARE CURRENTLY, AS OF 1:30PM MDT, MOVING
EAST THROUGH SOUTH-CENTRAL MONTANA. EXPECT THESE SHOWERS AND
THUNDERSTORMS TO MOVE THROUGH EASTERN MONTANA THROUGH THE
AFTERNOON BEFORE COMING TO AN END THIS EVENING. THE MAIN RISK WITH
THIS ACTIVITY IS GUSTY AND ERRATIC WINDS, BRIEF HEAVY RAIN, AND
HAIL. CANNOT RULE OUT A FEW STRONG TO SEVERE THUNDERSTORMS TODAY,
AND HAVE ALREADY SEEN A FEW SEVERE WIND GUSTS OVER CENTRAL
MONTANA. OUTSIDE OF THIS ACTIVITY, THE MAIN CONCERN TODAY IS THE
WIDESPREAD WINDY CONDITIONS THAT ARE DEVELOPING ACROSS THE AREA.
HAVE ALREADY SEEN WIND GUSTS OF 25 TO 50 MPH (OUTSIDE OF A FEW
HIGHER CONVECTIVE WIND GUSTS), STRONGEST OVER THE FOOTHILLS WEST
OF BILLINGS. LOOK FOR THESE WINDS TO CONTINUE INTO THIS EVENING,
GRADUALLY SPREADING EAST THROUGH THE DAY. WHILE WINDS WILL SUBSIDE
TONIGHT, BREEZY CONDITIONS WILL CONTINUE OVERNIGHT GENERALLY
AROUND AND NORTH OF A LIVINGSTON TO BILLINGS TO EKALAKA LINE.
TUESDAY WILL BE ANOTHER WINDY DAY AS THE LOW PRESSURE SYSTEM
LIFTS TO THE NORTHEAST. WITH THIS, WEST TO NORTHWESTERLY WIND
GUSTS OF 20 TO 45 MPH ARE FORECAST, STRONGEST OVER EASTERN
MONTANA. WHILE MOSTLY DRY CONDITIONS WILL PREVAIL, A SHORTWAVE
TROUGH BEHIND THE LOW PRESSURE SYSTEM MAY BRING ENOUGH LIFT TO
SUPPORT ISOLATED SHOWERS OVER SOUTH-CENTRAL MONTANA DURING THE
DAY. WITH THAT SAID, THE DOWNSLOPING WINDS MAY LIMIT SOME OF THIS
ACTIVITY TO VIRGA. EITHER WAY, LOCALLY ENHANCED WINDS ARE POSSIBLE
UNDER SHOWERS OR VIRGA ON TUESDAY.
WITH THE WIND TODAY AND TUESDAY, ELEVATED FIRE WEATHER CONDITIONS
EXIST. TAKE CARE TO NOT CAUSE A SPARK!
WEDNESDAY INTO THURSDAY LOOK TO BE DRY DAYS AS TEMPERATURES WARM
BACK INTO THE 80S AFTER A COOLER DAY IN THE 70S ON TUESDAY. DURING
THIS TIME, THE COMBINATION OF BREEZY WINDS, LOW RELATIVE
HUMIDITY, AND WARM TEMPERATURES WILL LEAD TO LOCALIZED ELEVATED
FIRE WEATHER CONDITIONS, ESPECIALLY ON THURSDAY.
FRIDAY INTO THE WEEKEND, THE FORECAST BECOMES MORE UNCERTAIN.
HOWEVER, A WEATHER SYSTEM LOOKS TO IMPACT THE AREA IN SOME
FASHION DURING THIS TIME, BRINGING COOLER TEMPERATURES AND THE
CHANCE OF PRECIPITATION BACK TO THE AREA. WITH THIS, TEMPERATURES
MAY BE COOL ENOUGH FOR SOME EARLY SEASON SNOW IN THE MOUNTAINS.
STAY UP TO DATE WITH THE FORECAST THOUGH THE WEEK, ESPECIALLY IF
YOU HAVE PLANS IN THE MOUNTAINS NEXT WEEKEND. LA
